Specifically preferred for biological activity is Compound G of Preferred E which is: 2-(2,6-difluorophenyl)-4,5-dihydro-4-[4-(2-naphthalenyl)phenyl]oxazole . Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active than the others and how to separate stereoisomers. Accordingly, the present invention comprises racemic and optically active compound(s). The term optically active compound(s) includes individual stereoisomers, mixtures of stereoisomers enriched in one stereoisomer, and optically active mixtures of compounds. The term "fused bicyclic ring system" is defined as those ring systems which satisfy the Nickel rule, including 8- to 12-membered fused bicyclic ring systems containing 0 to 4 heteroatoms and 1 or 2 aromatic rings, examples include naphthyl, tetralinyl, quinolyl, isoquinolyl, quinoxalinyl, benzofuryl, isobenzofuranyl, benzothienyl, benzodioxolyl, benzoxazolyl, chromanyl, indolinyl, isoindolyl, thienofuranyl, and purinyl. The aromatic ring systems can be attached through any available carbon or nitrogen, for example, for naphthyl, the bicyclic aromatic ring system si 1-naphthyl or 2-naphthyl, for benzofuryl, the aromatic ring system can be 2-, 3-, 4-, 5-, 6-, or 7-benzofuryl, and similarly for the other bicyclic ring systems. In the above recitations, the term "alkyl" used either alone or in compound words such as "alkylthio" or "haloalkyl", denotes straight or branched alkyl such as methyl, ethyl, n-propyl, isopropyl and the different butyl, pentyl and higher isomers. Alkoxy denotes methoxy, ethoxy, n-propyloxy, isopropyloxy and the different butoxy, pentoxy, hexyloxy and higher isomers. Alkenyl denotes straight or branched chain alkenes such as vinyl, 1-propenyl, 2-propenyl and the different butenyl, pentenyl, hexenyl and higher isomers. Alkynyl denotes straight chain or branched alkynes such as ethynyl, 1-propynyl, 3-propynyl and the different butynyl, pentynyl, hexynyl, and the higher isomers. Cycloalkyl denotes cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. Cyanocyloalkyl denotes the carbocyclic rings above substituted by cyano. Alkylcycloalkyl denotes the above carbocyclic rings substituted with a straight or branchchained alkyl group. Cycloalkylalkyl denotes a straight or branch-chained alkyl group substituted by cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Alkoxyalkoxy denotes alkoxy substitution on alkoxy. Alkylcarbonyl denotes carbonyl with an attached straight or branch-chained alkyl group. Alkoxycarbonyl denotes carbonyl with an attached straight or branch-chained alkoxy group. The term "halogen", either alone or in compound word such as "haloalkyl", denotes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as "haloalkyl", said alkyl can be partially or fully substituted with independently selected halogen atoms. Examples of haloalkyl include CH2CH2F, CF2CF3 and CH2CHFCl. The terms "haloalkenyl" and "haloalkynyl" are defined analogously to the term "haloalkyl". The total number of carbon atoms in a substituent group is indicated by the "Ci-Cj" prefix where i and j are numbers from 1 to 16. For example, C4 alkoxyalkoxy designates the various isomers of an alkoxy group substituted with a second alkoxy group containing a total of 4 carbon atoms, examples including OCH2OCH2CH2CH3 and OCH2CH20CH2CH3. When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. DETAILS OF THE INVENTION Compounds of Formula I can be made from amino alcohols (or thiols) of Formula II and benzoic acid derivatives as shown in Scheme 1 (in Schemes 1-8, Q is defined as a phenyl ring optionally substituted as defined above with R3, R4 and R5). The transformation generally consists of two steps. First, the compound of Formula II is condensed with the benzoic acid derivative to form an amide of Formula m. A generally useful way to do this is to treat the compound of Formula II with an aroyl chloride in the presence of an acid acceptor (usually a tertiary amine base such as triethylamine) at room temperature or below. This reaction can be carried out in an inert solvent such as dichloromethane, tetrahydrofuran, toluene, and other solvents that will not react with acid chlorides or bases. There are other useful ways to form amides, many examples of which are found in Larock, "Comprehensive Organic Transformations," VCH New York, pp 972-981. The second step carried out is the ring closure. This can be accomplished by treating the intermediate amide of Formula III with a dehydrating agent. Some useful reagent systems for this transformation include but are not limited to triphenyl phosphine/carbon tetrachloride, diethylazodicarboxylate/triphenyl phosphine, and thionyl chloride. An especially useful method for ring closure involves treatment of the amide with thionyl chloride in benzene or other inert solvent at reflux until the starting material is consumed (usually 30 min to 3 h). The residue of this reaction is treated with an inorganic base such as sodium or potassium hydroxide in an alcoholic or aqueous medium (usually heating to reflux for 30 min to 2 h is required). Many methods for ring closure to oxazolines have been compiled by Frump (Chemical Rev. (1971) 71, 483-505).

First, compounds of Formula IV are amidoalkylated with a compound of Formula V to form Formula VI compounds. A typical reaction involves the combination of compounds of Formulae IV and V in an acid such as sulfuric acid, methanesulfonic acid, trifluoroacetic acid, polyphosphoric acid and perchloric acid. The reaction can be run in a cosolvent such as acetic acid. The reaction temperature can range from -10" to 200 "C with 0 - 100 OC being preferred. Alternatively, the reaction can be carried out in an inert solvent such as chloroform, methylene chloride, benzene, toluene and ether in the presence of a Lewis acid such as aluminum chloride or boron trifluoride. The acid, temperature, and time of the reaction vary according to the relative reactivity of the Q group towards electrophilic substitution reactions. Amidoalkylation reactions have been extensively reviewed in the literature (see Zaugg, Synthesis (1984) 85-110). The second step is the reduction of a Formula VI compound to form a Formula m compound. Reductions of this type are well-known in the art (see Hudlicky, Reductions in Organic Chemistry (1984) 136-163). Typical reducing agents include the alkali metal borohydrides and diborane. When V is a lower alkyl group, the use of lithium borohydride as reducing agent, tetrahydrofuran as solvent and performance of the reactions at 65 "C for 1-6 h, is preferred.

This procedure is known in the art (see Ben-Ishai, Tetrahedron (1975) 31, 863-866 and Tetrahedron (1977) 33, 881-883).

In the reduction process, aminoesters are preferred, but amino acids themselves can also be used. There are many reagents known to reduce acids and esters to alcohols. (See Larock, loc. cit., pp 548-553). Particularly useful are alkali metal hydrides and boranes. For example, treatment of a compound of Formula IX with lithium aluminum hydride at 0-50 "C in ethereal solvents such as tetrahydrofuran, ether, or dimethoxyethane gives an alcohol of Formula II.

Useful compendia of methods for their synthesis are contained in Kukolja (J. Med. Chem. (1985) 28, 1886-1896), Bohme (J. Med. Chem. (1980) 23, 405-412), and O'Donnell (Tetrahedron Lett. (1989) 30, 3909-3912) and references cited within. Oximo esters of Formula X are especially suitable intermediates for the synthesis of compounds of Formula I. They can be made from aryl acetic esters of Formula XI by reaction, in the presence of base, with nitrosating agents such as inorganic and organic nitrites as shown in Scheme 6. Typically, the compound of Formula VI is treated with an alkyl nitrite such as butyl nitrite in an alcoholic solvent such as ethanol in the presence of a strong base such as sodium ethoxide at the reflux temperature of the solvent.

Aryl glyoxalates can be made by the reaction of an organometallic species with a derivative of oxalic acid. For instance, diethyl oxalate can be treated with an aryl grignard reagent at low temperature in ether/tetrahydrofuran mixtures (Rambaud, et al., Synthesis (1988) 564-567).

Monoesters of oxalyl chloride react with electron-rich aromatics of Formula XIII in the presence of Lewis acids to give compounds of Formula XII. See Olah Ed., "Friedel-Crafts and Related Reactions," Vol. 3, Part 1, pp 1 - 16. Treatment of compounds of Formula XIII with aluminum chloride and ethyl or methyloxalyl chloride in an inert solvent such as dichloromethane, nitrobenzene, carbon disulfide, or dichloroethane will produce compounds of Formula XII. Scheme 8 Compounds of Formula I in which R3 = OR12 can be synthesized as shown in Scheme 9. A compound of Formula XIII may be alkylated by a substituted alkylhalide or sulfonate XIV in the presence of an acid acceptor. The reaction can be carried out in a variety of inert polar aprotic solvents such as acetonitrile, dimethylformamide, dimethylacetamide, dimethylsulfoxide, and 2-butanone. Suitable acid acceptors include both organic and inorganic bases such as alkali hydrides, carbonates, and hydroxides. A preferred base and solvent combination is potassium carbonate in dimethylformamide. The process can be carried out from 0-150 "C, preferably at 25 "C.

To synthesize amides and esters the compound of Formula XV is treated with an alcohol XVI or amine XVII under an atmosphere of carbo monoxide in the presence of a palladium catalyst and a phosphine ligand in a dipolar aprotic solvent such as dimethyl sulfoxide or dimethylformamide. The reaction can be carried out at 25-120 "C and preferably at 65-70 "C for 2-5 h. The preferred catalyst system is palladium acetate and diphenylphosphinopropane.

The utility of organotin compounds in ketone synthesis has been reviewed see Synthesis (1992) 803-815 and Angewandte Chemie., Int. Ed. Engl. (1986) 25, 508-524. Organoboron compounds can also be used to make ketones; see Ishiyama et. al. Tetrahedron Lett. (1993) 34, 7595-7598 and references cited therein.

Organometallic reagents can be coupled with compounds of Formula XV with palladium, copper, or nickel catalysis. The organometallic reagent XIX can be chosen from a wide variety of metals including tin, zinc, magnesium, and boron. Tamao has summarized a range of different catalysts and conditions for these coupling reactions in Comprehensive Organic Synthesis; B. M. Trost Ed., Pergamon, (1991) Vol. 3, 435-520. Specific conditions and reactions of heterocyclic compounds in palladium and nickel catalyzed coupling reactions can be found in Kallinin, Synthesis (1992) 413-432. The synthesis of XIX (where Met is Zinc) can be accomplished in many ways, and a review of these conditions and procedures can be found in Knochel, Chemical Reviews (1993) 93, (2117-2188). The synthesis of XIX (where Met is Sn) is found in Synthesis (1992) 803-815 and Angewandte Chemie., Int. Ed. Eng. (1986) 25, 508-524. The synthesis of XIX (where Met is B(OH)2) is found in Ali et. al., Tetrahedron, (1992) 37, 8117-8126, and references cited therein. The starting materials for these compounds where R3 is a fused bicyclic ring system are known. Methods for the synthesis of compounds containing heteroatoms in the bicyclic ring system is found in Katritsky and Rees Eds., "Comprehensive Heterocyclic" Vol. 2-6 Pergamon, New York, (1984) and in Coffey Ed., "Rodd's Chemistry of the Carbon Compounds" Vol. IV a-l, Elsever, Amsterdam, (1973-1980). The chemistry of other bicyclic ring systems can be found in European Patent Publication EP-A-350,846; Berlin et. al., J. Med. Chem., (1985) 28, 116-124; Dawson et. al., J. Med Chem. (1984) 27, 1516-1531 and Olah, loc. cit., Vol. 2, 785-952. The chemistry and synthesis of naphthalenes is known and can be found in Coffey, loc. cit., Vol. III q, 99-284. Scheme 11 Met =Zn, Mg, rental catalyst = Ni, Pd orCu U, Sn, B, Compounds in which R3 is alkenyl or alkynyl optionally substituted with R9 can be made as shown in Scheme 12. Compounds of Formula XV can react with alkenes (XX) or alkynes (XXI) in the presence of palladium catalysts. This sequence is known as the Heck reaction and has been discussed in great detail by Heck in "Palladium Reagents in Organic Synthesis"; Academic, London, 1985. Other more recent modifications of this reaction are summarized in Larock and Baker, Tetrahedron Lett. (1988) 29, 905-908 and in Cabri et. al. J. Org. Chem. (1992) 57, 3558-3563. Typically, the compound of Formula XV and palladium acetate (1-5 mol %) and triphenyl phosphine (2-10 mol %) are heated with the alkene (XX) (1 to 3 equivalents) in dimethyl formamide or other aprotic solvents at 60-120 C. The presence of a base such as triethylamine, sodium acetate, sodium carbonate or potassium carbonate is required. When an alkyne (XXI) is used, the presence of a catalytic amount of CuI (1-5 mol %) accelerates the reaction. In this case it is often preferable to carry out the reaction using an organic base (i.e. triethylamine) as the solvent. Under these conditions the reaction with alkynes (XXI) often proceeds without external heating.

In these instances, the incorporation of protection/deprotection sequences into the synthesis will aid in obtaining the desired products. The use and choice of the protecting group will be apparent to one skilled in chemical synthesis. EXAMPLE 1 2-(2.6-DifluoroDhenvl)-4.5-dihvdro-4- cvclopentvloxvphenvl) oxazole Step A: Methyl ((2.6-difluorobenzovl)aminolhydroxyacetate A solution of glyoxylic acid monohydrate (37.2 g) was stirred in methanol (125 mL) and after 72 h the solvent was evaporated. The residue was dissolved in benzene (150 mL) and heated to reflux with 2,6-difluorobenzamide (44 g). After 16 h the cooled reaction mixture was diluted with benzene (100 mL) and filtered. Air drying left 64 g of crude product which was used without further purification: 1H NMR (CDCl3, 200 MHz), 8 9.7 (1H), 7.5 (1H), 7.2 (2H), 6.9 (1H), 3.7 (3H). Step B: [(4-Cyclopentyloxy)-&alpha;-[(2,6-difluorobenzoyl)amino] benzenemethanol Cyclopentyloxybenzene (4 g) was dissolved in trifluoroacetic acid (30 mL) treated with the compound of Step A (6.4 g) and stirred for 18 h at room temperature. The solvent was evaporated and the residue was partitioned between dichloromethane and saturated aqueous sodium bicarbonate. The organic layer was separated and dried. The residue was subjected to silica gel chromatography with hexanes/ethyl acetate (3:1 to 2:1) as eluent to give an oil (2.9 g). The oil was dissolved in tetrahydrofuran (20 mL) and treated with lithium borohydride (4.2 mL of 1N solution in tetrahydrofuran). The mixture was heated at reflux for 4 h. The cooled mixture was decomposed by the slow addition of 1N hydrochloric acid until the evolution of hydrogen ceased. The reaction was then diluted with water and extracted with dichloromethane. The residue was subjected to chromatography on silica gel with hexanes/ethyl acetate (2: 1) as eluent. The first spot to elute was the ortho-cyclopentyloxy product. The second spot (1.5 g) was the 4-cyclopentyloxy product: 1H NMR (CDC13, 200 MHz), Ï 7.3-6.9 (ArH), 6.7 (NH), 5.3 (1H), 4.8 (1H), 3.9 (2H), 2.2-1.7 (8H). Step C: 4- [4-(Cyclopentyloxy)phenyl] -2-(2 .6-difluoroDhenvl)9 .9dihvdrooxazole The compound of Step B was dissolved in toluene (20 mL), treated with thionyl chloride (1.8 mL) and heated to reflux for 1 h. The solvent was evaporated and the residue was dissolved in methanol (25 mL). Sodium hydroxide (2 mL of 50% aqueous solution) was added and the mixture refluxed for 1 h. The solvent was evaporated and the residue partitioned between dichloromethane and water. The organic layer was separated, dried and evaporated. The residue was subjected to chromatography on silica gel with hexanes/ethyl acetate 5:1 as eluent to give the title compound (1.0 g) as an oil: lH NMR (CDCl3, 200 MHz), 6 7.3-6.9 (ArH), 5.4 (1H), 4.8 (2H), 4.3 (1H), 1.9-1.6 (8H). EXAMPLE 2 2-(2,6-Difluorophenyl)-4,5-dihydro-4-(4-iodophenyl)oxazole The compound of Step A of Example 1(31.0 g, 0.13 mol) and iodobenzene (40.2 g, 0.19 mol) were suspended in sulfuric acid (100 mL) and stirred for 3 days at 23 C. The mixture was poured onto ice and extracted with dichloromethane (200 mL). The dichloromethane layer was dried over magnesium sulfate and evaporated under reduced pressure. Methanol (200 mL) and thionyl chloride (6 mL) were added and the mixture and heated at reflux for 30 min. The methanol was removed under reduced pressure and the residue was dissolved in tetrahydrofuran (200 mL).

compounds of Formula I as previously defined. Compounds of this invention will generally be used in formulation with an agriculturally suitable carrier comprising a liquid or solid diluent. Useful formulations include dusts, granules, baits, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry flowables and the like, consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up 100 weight percent. Weight Percent Active Ingredient Diluent Surfactant Wettable Powders 5-90 0-74 1-10 Oil Suspensions, Emulsions, 5-50 40-95 '0-15 Solutions, (including Emulsifiable Concentrates) Dusts 1-25 70-99 0-5 Granules, Baits and Pellets 0.01-99 5-99.99 0-15 High Strength Compositions 90-99 0-10 0-2 Typical solid diluents are described in Catkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. Typical liquid diluents and solvents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, and the like. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer mill or fluid energy mill. Water-dispersible granules can be produced by agglomerating a fine powder composition; see for example, Cross et al., Pesticide Formulations, Washington, D.C., 1988, pp 251-259. Suspensions are prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-148, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546.

The compounds of this invention exhibit activity against a wide spectrum of foliar-feeding, fruit-feeding, stem or root feeding, seed-feeding, aquatic and soil-inhabiting arthropods (term "arthropods" includes insects, mites and nematodes) which are pests of growing and stored agronomic crops, forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, and public and animal health. Those skilled in the art will appreciate that not all compounds are equally effective against all growth stages of all pests. Nevertheless, all of the compounds of this invention display activity against pests that include: eggs, larvae and adults of the Order Lepidoptera; eggs, foliar-feeding, fruit-feeding, root-feeding, seed-feeding larvae and adults of the Order Coleoptera; eggs, immatures and adults of the Orders Hemiptera and Homoptera; eggs, larvae, nymphs and adults of the Order Acari; eggs, immatures and adults of the Orders Thysanoptera, Orthoptera and Dermaptera; eggs, immatures and adults of the Order Diptera; and eggs, junveniles and adults of the Phylum Nematoda.

See WO 90/10623 and WO 92/00673 for more detailed pest descriptions. Compounds of this invention can also be mixed with one or more other insecticides, fungicides, nematocides, bactericides, acaricides, growth regulators, chemosterilants, semiochemicals, repellants, attractants, pheromones, feeding stimulants or other biologically active compounds to form a multi-component pesticide giving an even broader spectrum of agricultural protection. Examples of other agricultural protectants with which compounds of this invention can be formulated are: insecticides such as avermectin B, monocrotophos, carbofuran, tetrachlorvinphos, malathion, parathion-methyl, methomyl, chlordimeform, diazinon, deltamethrin, oxamyl, fenvalerate, esfenvalerate, permethrin, profenofos, sulprofos, triflumuron, diflubenzuron, methoprene, buprofezin, thiodicarb, acephate, azinphosmethyl, chlorpyrifos, dimethoate, fipronil, flufenprox, fonophos, isofenphos, methidathion, metha-midophos, phosmet, phosphamidon, phosalone, pirimicarb, phorate, terbufos, trichlorfon, methoxychlor, bifenthrin, biphenate, cyfluthrin, tefluthrin, fenpropathrin, fluvalinate, flucythrinate, tralomethrin, imidacloprid, metaldehyde and rotenone; fungicides such as carbendazim, thiuram, dodine, maneb, chloroneb, benomyl, cymoxanil, fenpropidine, fenpropimorph, triadimefon, captan, thiophanate-methyl, thiabendazole, phosethyl-Al, chlorothalonil, dichloran, metalaxyl, captafol, iprodione, oxadixyl, vinclozolin, kasugamycin, myclobutanil, tebuconazole, difenoconazole, diniconazole, fluquinconazole, ipconazole, metconazole, penconazole, propiconazole, uniconzole, flutriafol, prochloraz, pyrifenox, fenarimol, triadimenol, diclobutrazol, copper oxychloride, furalaxyl, folpet, flusilazol, blasticidin S. diclomezine, edifenphos, isoprothiolane, iprobenfos, mepronil, neo-asozin, pencycuron, probenazole, pyroquilon, tricyclazole, validamycin, and flutolanil; nematocides such as aldoxycarb, fenamiphos and fosthietan; bactericides such as oxytetracyline, streptomycin and tribasic copper sulfate; acaricides such as binapacryl, oxythioquinox, chlorobenzilate, dicofol, dienochlor, cyhexatin, hexythiazox, amitraz, propargite, tebufenpyrad and fenbutatin oxide; and biological agents such as entomopathogenic bacteria, virus and fungi. In certain instances, combinations with other arthropodicides having a similiar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Arthropod pests are controlled and protection of agronomic, horticultural and specialty crops, animal and human health is achieved by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of foliar and soil inhabiting arthropods and nematode pests and protection of agronomic and/or nonagronomic crops, comprising applying one or more of the compounds of Formula I, or compositions containing at least one such compound, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. A preferred method of application is by spraying. Alternatively granular formulations of these compounds can be applied to the plant foliage or the soil. Other methods of application include direct and residual sprays, aerial sprays, seed coats, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds can be incorporated into baits that are consumed by the arthropods or in devices such as traps and the like. The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food, depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, and synergists and other solvents such as piperonyl butoxide often enhance compound efficacy. The rate of application required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.001 kg/hectare may be sufficient or as much as 8 kg hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. The following TESTS demonstrate the control efficacy of compounds of this invention on specific pests. "Control efficacy" represents inhibition of arthropod development (including mortality) that causes significantly reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Tables A and B for compound descriptions.

TEST A Fall Armyworm Test units, each consisting of a H.I.S. (high impact styrene) tray with 16 cells were prepared. Wet filter paper and approximately 8 cm2 of lima bean leaf is placed into twelve of the cells. A 0.5 cm layer of wheat germ diet is placed into the four remaining cells. Fifteen to twenty third-instar larvae of fall armyworm (Spodopterafrugiperda) were placed into an 8 ounce (230 mL) plastic cup. Solutions of each of the test compounds in 75/25 acetone/distilled water solvent were sprayed into the tray and cup. Spraying was accomplished by passing the tray and cup, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 p.s.i. (207 kPa). The insects were transferred from the 8 ounce cup into the cells of the H.I.S. tray (one insect per cell). The trays were covered and held at 27"C and 50% relative humidity for 48 h after which time readings were taken on the twelve cells with lima bean leaves. The four remaining cells were read 7 days later for delayed toxicity readings. Of the compounds tested, the following gave control efficacy levels of 80% or higher: 6, 7, 8, 9, 12*, 14, and 15. * - tested at 250 ppm. TEST B Tobacco Budworm The test procedure of TEST A was repeated for efficacy against third-instar larvae of the tobacco budworm (Heliothis virescens) except that three 8 ounce (230 mL) plastic cups with wheat germ diet were used in place of the H.I.S. tray, with each cup pre-infested with 5 third-instar larvae. Of the compounds tested, the following gave mortality levels of 80% or higher: 25. TEST C Larval two-Spotted Spider Mites (Tetranvchus urticae) Solutions of the test compounds were prepared by dissolving in a minimum of acetone and then adding water containing a wetting agent until the concentration of the compound was 50 ppm. Two-week old red kidney bean plants infested with two-spotted spider mites eggs were sprayed to run-off with the test solution using a turntable sprayer. Plants were held in a chamber at 25 "C and 50% relative humidity. Of the compounds tested, the following gave mortality levels of 80% or higher seven days after spraying: 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 17, 18, 25, 26, 27, 29, 30, 31, 33, 35, 36, 37, 38, 39, 40 and 41. TEST D Fall Armvworm Whole Plant Test Solutions of the test compounds were prepared by dissolving in a minimum of acetone and adding water containing a wetting agent until the concentration of the compounds was 30 ppm. Test compounds were then sprayed to run-off onto soybean plants utilizing a rotating platform and an atomizing sprayer. Treated plants were dried, and fall armyworm (Spodopterafrugiperda) larvae were exposed to excised, treated leaves. Test units were held at 27 "C and 50% relative humidity, and evaluated for larval mortality 120 h post-infestation.
